lChe present application has to do with a new and novel method of aanufacturing metallic ammonium oxide compounds.

One object of the preset invention is to provide a new and novel method for manufacturing such compounds.

Another object is to provide such compounds for use in processes of textile treatment such as that set forth in my copending application derial Number 581,50l filed December 16, 1931. I

5 their objects Will become apparent from a study of the following specification and claims.

iiiccording to the present invention, metallic ammonium oxioe compounds are produced by employing acids derived from the higher degrees of oxidation of amphoteric metals, i. e., through the double decomposition of ammoniacal metallic oxide salt solutions with the alkali salts of the corresponding acids. As an example, either sodium aluminate or sodium zinc-ate may be employed for this purpose.

The chemical conversion takes place in the following manner: An ammoniacal metallic oxide salt plus sodium aluminate, produces an ammoniacal metallic aluminum oxide plus a sodium salt. For example:

I have found that the solutions thus manufactured can be obtained in a high concentration, and consequently possess ahigh de gree of effectiveness. Such solutions are eminently suitable in the treatment of textile materials, particularly artificial silk textiles, in Order that a Weighting or Waterproofing may be effected. In the process, the material to be treated is Well and uniformly soaked in the solution and then Well dried in order to volatilize the ammonia. I have found that by the selection of the proper metals an antiseptic effect may also be imparted to the textile.

The process is empirically explained by the following specific example. he metals of the ammoniacal metallic oxide compound ,hSerial No. 614,621, and in Germany June 3, 1931.

and of the alkali salts derived from metallic oxides, maybe varied or replaced, as desired.

Ewmnple.24i0 grams of nickel sulphate are dissolved in 9320 cubic centimeters of a l415% solution of ammonia, and 680 cubic centimeters of an aluminate solution containing 68 grams of sodium hydroxide and 2.5 grams of aluminum are added, under agitation. A Bordeaux-red liquid is obtained which may be used directly, if pure reagents have been employed, or after filtration, if the reagents employed Were such as to render filtration necessary.

As pointed out above, the metals used may be varied. his is shown by the following:

3Cu (NI-I SO 2Na AlO (Cu (NIL) 3 (A10 3Na SO Ni (N113) eo. x znoze I Z11O2 K2804 I have found that the presence of sodium sulphate in the bath does not have a bad effect on the Weighting of the textile materials. Also, it may be easily removed by means of Washing, after the ammonia has been evaporated.

Having now set forth my invention as required by the patent statutes, What I desire to claim is:

1. In the production of metallic ammonium oxide compounds, the step of treating a metallic ammonium oxide With an alkali salt.

2. In the production of metallic ammonium oxide compounds, the step of treating a metallic ammonium oxide With an alkali salt derived from the higher oxidation of a more amphoteric metal.

' 8. A Weightin g compound for textiles comprising an ammoniacal metallic aluminum oxide.

4. A Weighting compound for textiles comprising an ammoniacal metallic zinc oxide.

5, A Waterproofing and Weighting agent zineate solution containing sodium hydroxide and zinc.

9. In the production of a Weighting and Waterproofing material for textiles, the steps of dissolving a metallic salt in ammonia, and adding thereto an'aluminate solution.

10. In the production of a Weighting and Waterproofing material for textiles, the steps of dissolving a metallic salt in ammonia, and adding thereto a zincate solution.

In Witness whereof I afix my signature.
